| The Bottom Line | Windows Defender is free and therefore should be a part of your desktop antispyware collection. | AVG Anti-Virus 8 is solid at finding and removing viruses and spyware as well as blocking Web threats, but could be lighter on system resources and provide more technical support options. | At $20, ZoneAlarm Anti-Spyware is one of the least expensive paid antispyware option we reviewed, offers more features than other similar products, and remains one of the best. | Spyware Doctor 5.1 could be more aggressive in removing all traces of found spyware. | |
